"Speaker Pelosi thinks 'he’s just not worth it?' " Steyer asked in a statement. "Well, is defending our legal system 'worth it?' Is holding the President accountable for his crimes and cover-ups 'worth it?' Is doing what’s right 'worth it?'

Steyer has poured millions of dollars into the "Need to Impeach" campaign to remove Trump from office, airing television ads and holding town hall events to pressure Democratic lawmakers over the issue.

His latest statement came shortly after The Washington Post published an interview with Pelosi in which she offered some of her strongest remarks yet against impeaching Trump.

"Impeachment is so divisive to the country that unless there’s something so compelling and overwhelming and bipartisan, I don’t think we should go down that path, because it divides the country. And he’s just not worth it," Pelosi told the Post.

Pelosi said that despite her opposition to impeachment at the moment, she does not believe Trump is fit to serve as president.

"Are we talking ethically? Intellectually? Politically? What are we talking here?" she said. "All of the above. No. No. I don’t think he is."

The issue of impeachment has divided Democrats since they retook control of the House in January.

Party leaders, including Pelosi, have largely sought to tamp down the issue, arguing that lawmakers should take a wait-and-see approach as special counsel Robert Mueller and congressional committees conduct ongoing investigations.
